To all whom it may concern: t f

Be it known that LCLAUnii HENRY' NissvAii'r, a subject of the KingofSweden, .zand resident of Rock Island,v Illinois, United States ofAmerica, haveA iuventeda l certain new and useful Improvement inSeed-Dropping Mechanism, of which the following is speeiieation. 1

lilly `invention relates to seed dropping niechanism,and.nioreparticularly to the seed dropping mechanism employed for planting cern,such., or exemplaar that used in the checkr0w corn planter.

relates especially to.y that construction rotar .seed droppingmechanisminwhich .so-called seed ring is emplo ed--that-.isto e ring'having seed ce ls` or notches therein, .whereby the 4corn- `isdischarged cdgcwise, amachine of this Ikind bein `commonly known asari..ledgedropA` p unter. Ciiie sadlr'in is actuated in a rotary manner,and the ernels ofcorn are carried by the cells or notches .toaapointwhere `they are drop ed or discharge drop planter, whereb nels ispredetermine though of course, such mechanism can also he for drillino'.In a particular yforni oit seed dropping mechanism thesaid cells ornotches are formedy atthe extreme outerv edge o the ring, and the massof corn is su ported in the hopper in contact `with-t e ring, so thataslt e latter revolves kernel of cornwill settle into Teach eellor notchin an edgewise manner, and thenbe csrricd around to the `point offdischarge. in e mechanism of this kind the seed or corn does not alwayssettle iroperly into the cells or notches,as it sometimes happens thatthe lreinels'do not ente'r edgewise, andthis intori-eros with the properplanting o the corn. Also, with the o d form of edge-.dro i mechanismthe round kernels had a ten oney to collect or accumulate at-'thcbottoni o the ho per.

fin object ci) my invention is, therefore, to provide an improved seedring having ineens whereby the corn willbe agitated or sctedguponin::iueli'a mannen at the bottom otlie liopper-that'eaeh cell ornotchyinthe will` always be lled,`. as-l the; :result .of f. the roteti'onottheriiig, and whereby-'the kernels willbe* more surely and 'evenlyVspeiniziatica b: aderiranno i 'Patented-Nor. as, spinnen@ anni'september afieio; ,'sevriai no.' sarees.

The edge-drop` is particularly effective inzan accumulative.' thenumber-off kerfor each .hil1;al'

a single i 4 H f i. i turnededgewise than heretofore, thus insuring amore vuniform planting of the corn.

1-. Another. object is to provide an arrange ment whereby round kernelswill pass readilylinto `the cells or notches, at the point of cut ofi,s'o that such kernels will not tend to accumulate: at the bottom of thehopper.

Figyi is a bottom i plan of themechanism shown in Fi .-1, with the geen ing removed, and showing thesupporting ringE in dotted lines.

lCAS thus illustrated, the seed mechanism comprises the usual ho per Afor holding the corn, which hopper as a stationary bottom plate B, whichotter is provided at the discharge side of the mechanism with a bulge orraised portion b providing a cavity for the pivoted element or eut-oil1bl, which latter is shown in dotted lines in Fig. 1. This element orcut-cti' b1 is for the purpose of keeping the muss of corn fromfollowingr through to the point of discharge, and op-V erates in tlieusual und well known manner. The seed ringr C is disposed as usual atthe bottom of the hopper, und is provided with the usual lugs or teethc, which forni seed cells or pockets c1 between them. 'ihe ring hasinwardly projecting lugs c that remov ably engage t e gear wheel l)whereby thc mechanism is operated. A. removable ringe E supports theseed ring in the usual inunner, and prevents the corn .from 'felling`through except ut the mint of dischurue 'lheconstruction thus iurdescribed is `nl old and well known.

.iOne yifeatureof 'iioveltv consists in tli flange orrim cMvhicli isorincd around th Vperiphery' ofthe ring, and which project upwardly anylsuitable distance, us showi in the drawings.'

in the hopper. During this time these kernels are irevented by theflange or rim trom failing over and heine; discharged through kernels inthe cells. l1`urthcrmore, the said flange or run c serves to agitate thekernels the usual channel along with the'v ot corn et the bottom of thehopper andi turn the .same surely and evenly gti-Wise into the cells orpockets c, as the ring rot tetes. lin this way there is greatercertainty then heretofore of each cell or pocket being ,iiled'as itmoves around, as there is lncressed agitation Aof the kernels at thebottom of the ho per, nndincreased certainty of the kerne s bein turnededge-wise as they enter the cells, w ich, of course is the desired modeof operation of an edge drop. onsoquently, a kernel of corn is alwaysdropped from nach cell -or pocket, having entered edge-wise therein, andthe' plnntxng is more uniform.. By reason ofthe tengeor rim c there18,'s0to speak,'elsherp q linefozt demmcetionv between the` corn inlandshove the cells 'or pockets and the-corn which iscn and above the bottomplete B. Furthermore, end es stated, the said flange Orsini-*provides ncontinuous support. for thelcornfwhich produces a more effectiveagitation of the same, as distinguished from `[eseeddropping mechanismof this kind in -which the teeth c are the only portions ot the ringwhich support the corn. its stated, theref0re,each cell or pocket ismore certnin to till, and there is greater certainty oi oni" one kernelbeing discharged from each cell or ocket. Consequently., yincircoli-rowing` which-requires a redetermined number of kernels for eachill, there is greater certninty of enchhil-l having the same number 0fkernels. There is also another trouble which my invention obviates.Prior to my invention, the round kernels tended to acoumulnte in thebottom of the hopper. This was because the cells could not readilyreceive the round kernels, and so they tended to collect at the bottomof the hopper. lrovision was made, however, for discharging any roundkernels that might vaccidentally become wedged into the cells. icorrer-t this diiiienlty in the following manner: lho rigid'orstationary ho )per ring trl, which encircles the seed ring, es aclearance f/ on the rinner lower edge thereo', which extends from npoint n-bout under the beveled rnd oi the "cut-oli? b1 to the point ofdischarge at (7, es shown in Fig. 2. lhus any round kernels which nosunder the cut-oil" nro iustnntly Inllowet to settle to the bottom of`thei cel-1e, 'and in this way travel around rmt-il they fall at g1.

0n the upper linside edge of the outside ring Ge slight recess H tendsto facilitate the-passage of the corn under the beveled endof thecut-off b1. rThus, with my improved lconstruction, provision is not only'mode *for-releasing the round kernels il they do happen `to grt intothe cells, us wos llormerly the ense, but provision is also uuulefor/getting the round kernels properly und easily into thecells. lliememy invention, it.

wus un accident. when a round kernel got into ve. cell in an edgedropplanter. New. und my invention, it is possible to Afeed the roundkernels into the cells without in any way interfering with the edgeoviseiutroductlon of the regular kernels into the oeils. By regular kernels Imean the kernels from the middle of the eur of corn. An ordinaryedge-drop planter is saftisiiuxtorv when the lcorn is selected; butfarmers as a 1 class do not. do this, but. put in everything.

Consequently, in nn ortinary edge-drop planter, the round kernels tromtho butts ,end to accumulato in the bottom ot the hopper.` With -myinvention, however, the round kernels, as explained, een ,fro ousilvunder 'the cut-oli', and then instuuHy settle Y, intoplace at the bottomof the cells. in this Waythc diliiculty of using uuselected corn lll4lli

f tory seed ring having its peri um HC-Nedsites 'uw' messes in :inedge-drop planter is entirely over-y come. The clearance g, which growsWider ne it approaches the oint of discharge, and which is a littlewider atliottom than et iop, permits the round kernels to pass from thepoint cient-off to the point of discharge without. grinding or rabbins.
